Title: Load weight corresponding type speed control method
Inventor: OKADA TETSUJI
IPC: B23Q15/00
Filed: 1989-07-26
Abstract: PURPOSE:To realize a speed-up at the weight tool changing time by limiting the output at acceleration time to the value equivalent to a light tool and operating at the optimum speed corresponding to the transfer weight, in the case of controlling the tool changing speed of a machining center. CONSTITUTION:A servomotor is actuated by limiting the output at an acceleration time to the acceleration torque limited value equiv. to the load of a light weight, achievable speeds V1, V2 which become slower as the load weight at a set acceleration completed position (a) is larger are detected and a speed command value is switched to this achieving speed. Now, when a heavy tool is held on a changing arm and the revolving at 180 deg. is performed by the servomotor, the delay against the acceleration command becomes larger. The achieving speed V2 of the commanded acceleration distance completion position (a) is detected now, the speed command value is re-written to V2 from V1, the arm is revolved at the designated speed V2 and deceleration is performed. Since the heavy tool reaches at the speed V2 to this deceleration start position and the light tool at the speed V1, they are smoothly decelerated and stopped at a target position.

Title: Ohmic contact electrode of semiconductor diamond
Inventor: ISHII MASAYUKI
IPC: H01L21/04
Filed: 1989-07-26
Abstract: PURPOSE:To provide a low-resistance ohmic contact on a semiconductor diamond by forming an electrode of a P<+> or an N<+> polycrystalline silicon film, or of an amorphous silicon film containing microcrystalline silicon. CONSTITUTION:As diamond has a large work function, when a high barrier is formed at a contact of a semiconductor diamond with metal or metal compound. Therefore, an ohmic contact can not be realized only by attaching metal or metal compound on the surface of diamond. Even if an ohmic connection is formed, the contact resistance is too high. Thereupon, a P<+> or an N<+> polycrystalline silicon film or an amorphous silicon film which contains silicon of microcrystalline phase is used as an electrode built on a semiconductor diamond. This provides an ohmic contact electrode having a sufficiently low contact resistance.

Title: Method and device for monitoring bus inside device
Inventor: HANBA CHIKAKO
IPC: H04L12/40
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To attain quick post processing such as the resending of a transmission signal by comparing a transmission signal to be outputted to a bus with a bus signal obtained by immediately inputting a signal outputted to the bus and detecting a bus fault. SOLUTION: When a bus fault occurs, an abnormal signal is inputted to a buffer 24. A comparing part 25 compares a transmission signal S20 with a bus signal inputted to the buffer 24 only for the output period of a control signal S26 from a control part 26. At the time of detecting non-cincidence between the signal S20 and the bus signal, the comparing part 25 detects the existence of a fault on the bus 21 as an ALM and the control part 26 resends the signal S20. In the case of storing plural packages, the output of the transmission signal S20 from the control part 26 to the bus 21 can be immediately confirmed without fail, so that post processing such as resending of the transmission signal S20 can quickly be executed.

When a call setting request is received from the CS, the outgoing number of the opposite incoming party is stored in the storing area with the communication data type stored in another storing area respectively. Then the call that is started by an incoming call is cut.  Furthermore, the ADT that is previously held is started to perform the outgoing operations based on each storing area.
